TO ALL WI'IOM I'l MAY C ONCERN:

Be it known that I, I-I. ILQMITCHELL, of Mineral Point, in the 'county of Iowa, and State of' Wisconsin, have invented a new and useful Improvement in Hand-Looms; and I do hereby declare that the following is a. full, clear, and exact description thereof, which will enableothcrs skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part of this specitication, in which- Figure l is a vertical longitudinal section of a loom taken in the line x x, tig. 2, showing my improvements.

Figure 2, a top view.

Figure 3, an enlarged detached view of my improved cam-roller for lifting the treadles.

Similar letters of reference indicate like parts.

This invention relates to improvements in a hand-loom, 'and consists in attaching a cord and weight for regulating the lnovementoi` the yarn-beam, in the pla-ee of the lever-arrangement in the improved hand-loom n for which Letters Patent havebeen granted to J. W. Hayse; and also in placing weights on the treadles, together with iron screw-pins or tappets in the rollers for operating the treadles, as hereinafter described.

A represents the frame of an ordinary hand-loom; B, the yarn-beam or roll; C, the cloth-beam; D, the breast-beam; E, the lay; F, the lieddles; G, the treadles;- and II, a reciprocating disk, hung loosely.on the shaft a, which, through. .a pawl Yattached thereto, engaging with a ratchet on the shaft, moves the cam-rollers m for the purpose of Working the treadles. The disk receives its motion from the lay by means ot' a connectingrod, e e. On the opposite side ot' e'aeh of the treadles G is placed a weight, g, and below the treadles, in the rollers m, for lifting them, are placed movable iron screws z, to serve as tappets, the object of which arrangee ment of iron screws is to allow them to he changed easily and quickly. The weight I, attached to one end ot' the cord c, fastened at the other end to the framing,.and-passin'g'over the pulley J on the yarn-beam, regulates its movement and lets the yarn unwind evenly, while it is much more easily managed than hy the lever commonly employed for the purpose. l

What I claim as new, and desire to secure by Letters Patent, is-

The combination and arrangement ot' tho lay E, supporting the take-up beam C, with the link c, looseratchet pulley H, shaft a, screw-pins 7:, and weightsg, all operating as described, for the pur-pose specified.
